ln the followingI specification, .only the improved parts are described in detail, While all the other parts, comprising the machine, are only described as far as they are connected with said improvements, since they are or may be the same las in the patent above referred to. Y

ln Figs. 1, 2, 3 andl 4; 1 1S the bed 0r frame on which the machine is mounted, and 2 is a vertical frame carrying on suitably shaped brackets 3 the eye hoppers 4. llongitudinally and centrally to the machine and transversely to frame 2 is mounted on bed l sewing table 5, within and on which .shown in Figs.

the card feeding mechanism, to be described later on, is mounted.

6 is the vmain driving pulley by which power is applied to the machine, and 7 is the main shaft. from Which the motion is equally l transmitted to both sides of themachlne in a similar manner to that described in the patent above referred to.

Since both sides of the machine are symmet rival, each side sewing one row of hooks and eyes on the card, only`one side Will be described in the following: The presser foot mechanism' for holding the pair of hooks and eyes in sewing position on the card after it has been' delivered by the gripper is illusf trated in Figs. 5, 6, 7, 8, 9, 10, 11, 12 and 13. ln Figs. 5 and 7 are shown the rocking shafts 10 and 11 mounted in bracket 8 fastened on cross bar 9 of frame 2, and operated by forked arms 12 and 13, respectively, from roller cams 14 and l5 mounted on shaft 7. Presser foot 21, details of which are shown in Figs. 8 and 9, is mounted on bar 24. disposed in a slide 22 which in turn is a part of slide 23 mounted dovetailed in bracket 8 to reciprocate parallel to the line ot' movement of the cards. Bar 24 extending through slide 22 is provided with a slotted head 1G engaging pin 25 of arm 26 mounted on rocking shaft 10. Slide 23 engages by its pin 27 in arm 28 mounted on rock shaft 11. the real'ward spring actuated motion of .slide 23 being limited by set screw 29. By this mechanism it will be vseen that foot 21 is enabled to perform a rectangular motion as follows: In the position 5 and 7 incline 30 of cam 14 is just about to throw forked arm 12 forward, which through arm 17, shaft 10 and arm 26 will cause the lifting of bar 24. and

thus the lifting of presser foot 21 from the sewing plate 5, in order to make room for the gripper, to be described later on, to place the next pair of hooks and eyes en the card. ln the meantime cam surface 33 of cam 15 will have approached roller 19 of forked arm 13 and by throwing this arm forward will, by moving arm 18 on shaft 11 and arm 28, cause slide 23 and thus presser foot 2l to move to the left toward the direction from which the card is fed, that is to say in this instance, toward the front of the machine, the end of the presser foo-t being at the end of this motion above the place Where the pair'of hooks and eyes has been' placed by t e gripper. Soon afterward cam surface 30 of cam 14 will have passed roller 20 of forked arm 12 and this arm will heretracted by spring 31 until roller 20 rides on cam surface 32 which will cause presser foot 2l to descend and take hold of the pair of hooks and eyes presented by the gripper in a manner to be described later on. ln the meantime cam surface 33 of cam 15 has passed roller 19, and forked arm 13 is retracted by spring 34 until roller 19 rides on' camvsurface 35, thereby moving slide 23 and with it presser foot 21 slightly to the right to convey the first pair of hooks and eyes from the line -ai in Fig. 3 on which they have been placed by ing line y-y/, it being understood thatv the card moves on sewing table 5 in Fig. 5 from the left to the right. The adjustment of presser foot 21 is so that when roller 20 rides on cam surface 32, presser foot 21 has indeed seized the pair of hooks and eyes, but has not pressed it down firmly on the card. The fixing of the hoo-ks and eyes in sewing position takes place as soon as roller 20 eaves cam surface 82 and rides on cam surface 36 which causes bar 24.-' to descend fart-her and hold the pair of hooks and eyes vfirmly on the card until a stitch has been made by the machine through the rst pair of sewing eyes, which are at that time in line with the needles. After the stitch has been made, roller 19 has reached the end of cam surface 35 and will ride now on surface 37, thereby causing slide 23 and presser foot 21 to move with the card one step farther to the right which is equal to the distance between two sewing,` eyes of each hoo-k and eye, so that thus the other pair of sewing eyes are presented to thc needles and the sewing of this pair of hooks and eyes may be completed. After the needles have been withdrawn from the card, cam surface 30 of cam 14 has arrived again at roller 20 of forked arm 12 and throws this arm forward, thus lifting presser foot 21 from the sewing table 5 making room again for the gripthe gripper to the sewl i per to present the next. pair of hooks and eyes and repeating the process as described above.

When the presser foot descends to seize a pair of hooks and eyes, the action takes place while the jaws are still holding the hook and eye, and the jaws then release the hook and eye to cause the engaging portion of the presser foot to maintain its ositive hold. The part 41 of the presser oot engaging the hook is disposed to move inde pendcntly of presser foot 21 in a. vertical direction and is pressed' yieldingly against the hook by a spring 42 shown in Figs. 5, 7 land 8.

It has been found that the .needles 43, shown in detail in Fig. 10, when leaving the card, after the second stitch has been made, tend to lift the card from the table since at that time presser foot 21 has left the pair of hooks and eyes to make room for the gripper. A card presser foot has been therefore provided which will press the card against the table while the stitch is made,- until the needles have been pulled out of the card. This device is shown in detail in Figs. 10,11 and 12, Needle bar 44 slidingly mounted in guide 47 of cross bar 9 (Fig. 2) is operated by rocking lever 45 suitably fulcrumed in frame 2 and engaging in yoke 4G of needle bar 44. Rocking lever 45 in turn is operated from shaft 7 in a similar manner to that described and shown in the patent above referred to. ln Fig. 10 are shown mounted on the needle bar guide 47 the guide plates 48 in which the rods 49 of card presser foot ,50 are disposed to have .vertical movement. These rods are further guided in brackets 51 `collars 54 fixed on rods 49.

mounted on needle bar cross arm 52. The card presser foot is pressed against table 5 by springs 53 abutting against brackets 48 ou `one end and on the other end against The adjustment of collars 54 is such that footl 50 is held against the card as long as the needles are in the stitch holes. Shortly after the needles have been withdrawn from the card, guide brackets 51 will strike in their upward 'motion together with needle bar .44 against. collars 54 and thereby lift foo-t 50 from the card, which lifting motion occurs early enough not to interfere with the gripper, placing the next pair of hooks rand eyes on the card.

The hook and eye chutes shown in Figs. l, 2, 22, 23, 24, 25, 26, 27, 28, 29, 30, and 32, comprise principally similar parts to those shown in the patent above referred to, and the improvements consist in devices pro vided in these chutes for feeding a single hook and eye at a time to the gripper. After a hook has been delivered tothe chute 55 in the manner described in the patent above referred to or otherwise, it slides down until it strikes pin 56 placed in the path of the hook-aud held in this position by' spring 61. On the under side of chute 55 is suitably disposed slide 57 engaging pin 56 with a slight lost motion and also carrying on the side opposite to pin 56 locking bar 60 disposed on said slide 57, so that when pin 56 retains the hooks delivered to the chute, locking bar 60 is out of the path of the hooks in the chute. This position is shown in Fi f. 22. lf now by suitable means, to be t .scribed later on, slide 57 is shifted to the' left, pin 56 Will'be taken along by the slide and thus release the hooks which will now move forward in the chute until the bill of the first hook kstrikes the locking'bar 60, which has been moved in the meantime by slide 57 into the path of the hooks. This position is shown in Fig. 25. If now slide 57 is returned to the right, pin 56 will first return into its locking position by means of spring 61, thereby retaining the second hook. 0n further movement of slide 57 to the right,

the first hook will be released from locking bar 60 and slide down to the end of the chute where it is held by leaf spring 62 ready to be taken by the gripper to be described later. While any number of hooks may have collected in the chute above pin 56, the feeding device above described will by its reciprocating motion feed only one hook at a time to vthe end of the chute.

The device for delivering the eye int-o position to be engaged by the bills of the hooks comprises the following mechanism. After the eyes have been dehvered by the eye receptacle, to be described later on, to rail 63 (Fig. 4) and have straddled down along on the bead 64 of this rail in a similar manner to that shown in the patent above referred to, they will arrive nally at the end of the rail shown in detail in Fig. 29. As ma be seen from this figure the end of the rai is suitably shaped to protrude into an' opening 73 of the device delivering the eye singly into the ath of the hook bills. l In said device (35 1s a bar which is suitably fastened on cross bar 9 of frame 2 and extends downwardly approaching the sewing table at a suitable angle shown in Figs. 13 and 29. The upper side of the end of bar 65 is provided with a recess 38 adapted to receive a slide shown in perspective view in Fig. 31, and is furthermore provided at its end with a narrow slot shown in Fig. 27 in plan view and in Fig. 29 in side View. The recess 38 which receives slide 70 is covered by plate (38, provided with a slot 71 through which a pin (i9 fastened on slide 70 protriules. Side arm 7 of plate 68 carries pivoted to it bell crank 67, one arm of which engages pin 69 of slide 70, While the other arm is pivoted to a slide 66, moving transversely to bar 65 in guide 72. At

.slide will be shifted the lower end of plate 68 is provided the opening 73 of suitable size and shape to have/ille eyes nnss through it when they are delivered by tile eye rail 63 protruding into said opening as mentioned before. 0n the under side ot' the end of bar 65 is fastened a spring 74, the tip of which protrudes into the narrow slot 75 near the end of bar 65, so that when an eye glides from rail 63 through opening 7 3 of plate 68 and rests on the bottom 77 of recess 38 of bar 65, it will be prevented from further gliding down by said spring 74. ln this position of theeye, slide 70 is drawn up to its higl'iest position as indicated in Fi 27. If now by suitable means to be described later, slide 66 is shifted to the right into a position indicated in Fig. 28, downward, thereby pushing the eye, which has been delivered by the rail in front of it, to the end of the feeding device which is suitably shaped to it the eye and prevent it from falling out, as may be seen in Fig. 28. l/Vhen in this position of the eye a hook is carried by the gri ppers from the right to the left (Fig. 29) its bill will pass through recess 39 provided at the end of bar 65, and engage the eye, and on further movement to the left lift same from its seat (shown in Figs. 28 and 29) and draw it out of the feeding device. On reverse motion of slide 70 another eye will drop down from the rail into recess 38 of the feeding device and be held there by spring' 74 buntil slide 70 is operated downward to deliver another eye into engaging position for the next hook, and so on.

ln the machine of the Rowbottom patent referred to, the hooks and eyes formino a pair have been delivered to the card by 1n- 'dividual grippers, so that two grippers disposed within each other were used to place a pair of hooks and eyes on the card, which involved a rather complicated mechanism. My improved gripper mechanism, however, comprises only one gripper for cach pair of hooks and eyes which has simplified this de vice considerably.

The gripper device (Figs. 1, 3, 13, 14, 15, 16,' 17 and 18), comprises a support 05 suitably mounted on bed plate 1, which contains the slide 96 disposed in a dove-tailed groove and operated by the connecting rod 97 pivoted on lug 98 of slide 96 and pivot-ed at its other end to lever 94, fulcrumed at 99 on bed plate 1. The shaft 7 (Fig. 3) is connected by miter-gears 100 to shaft 101, which carries the gripper-operating disks 102, 103 and 104. shown in detail in Figs. 15 and 16. Within slide 06 is disposed another slide 105, aside view of which may be seen in Fig. 15. AAt the right end of this slide is fastened cam roller 106, riding on cam 107 mounted on shaft 101, slide 105 being held in engagement with cam 107 by'spring 108. Lever 94 is provided with cam roller 109 which is disposed in cam rroove 110 of disk 104, so that lever 94 will be positively operated at all times. On slide 96 are fulerumed the two gripper arms 111 and 112, the ends of which are held in gliding engagement with disks 102 and 103, respectively by springs 113 and pins 114 (Fig. 17), disposed in recesses of slide96. The jaws of gripper arms 111 and 112 are shaped at thelr ends 116 suitably to receive the sewing eyes of the hook and also the eye in a recess 115. 0n slide 105 which is disposed in slide 96 4between the gripper arms, is mounted pusher 117, the different purposes of which are hereinafter' set fort-l1.

When as shown in Fig. 23 a hook has been delivered to the end of the chute, thereby Astriking leaf spring 02, which keeps the hook from prematurely slipping out of the chute, it has been found that the hook will slightly rebound on spring 62 and slide back on the surface of plate 118 of sewing table 5 into a position shown in this figure in full lilies. This rebound would cause the hook not vto be in the proper osition to be seized by the gripper' jaws at t 1e sewing eyes. 'lo insure-the proper seizing position of the hook at the end ofthe chute (indicated in dotted lines in Fig. is one of the purposes for which pusher 117 has been )revided. When (see Fig. 15), roller 106 rides on cam surface 119 of cam 107, the slide 105 and with it pusher 1.17 are retracted the farthest to the right. l/Vhen now, revolving in the directionof the arrow, cam 107 causes roller 106 to ride on its surface 120, pusher 117 will be moved -slightly to the left far enough to push the hook shown in Fig. 23 in full lines into the position indicated in dotted lines, for which purpose a groove 93 is provided on the under side at the end of hook chute 55 Fig. 26) of suitable size to have pusher 11 pass through it. In the meantime roller 109 of lever 94 is about to run up the incline of cam surface 110 as shown in Fig. 15. Disks 102, 103,r 104 and cam 107 are mounted on shaft 101 relatively te their cam positions, roller 106 has come into Contact with cam surface 120, thuscausing pusher 117 to push a hook into sewing position, the gripper arms 111 and 112, previously in contact withv the elevated portions 121 and 123 of disks 102 and 103 respectively, will come intol contact with the respective recessed portions 122 and 124 of disks 102 and 103, owing` to the expansion of springs 1.13 as above described. This causes the gripper jaws 116 to seize the hook, brought into proper position by pusher 117, at the sewing eyes. This relative position of the different parts of the gripper mechanism described above is indicated 1n Figs. 15 and 16. As already mentioned roller 109 is just about to roll up the incline of cam groove so that just after .stee

nagwhich will cause slide se with ie grip er arms and the seized hook' to move orward until roller 109 arrives at c am Asurface 125, which causes the gripper jaws .tov come into the proper position to place .the

hook and eye on the card. During this forward movement of the seized hook the bill of the hook will engage in the eye, delivered by the eye feedino' mechanism into the proper position as daescribed above, and the eye, taken along by the hook, will drop into recess 115 of the jaws, (Fig. 14).

To insure the dropping of the eye into recess 115, which is desirable in order to place a palr of hooks and eyes into the proper position to be received by .the eye presser foot, a brushing device is provided which brushes over lthe sewing eyes of the hooks and eyes, while they are shifted into' .th sewing position in the following mannerz; On bar 65 is fastened block 130 (Fig. 13)

the under side of which is suitabl recesse at 126 (Fi 32) yto have the b1ll of the hook pass t rough it. At the end of block rush a forked platey 130 is fastened 31 spring, the two ends o hich close that just enough space is left for he sewing eyes .of the hook and eye to assf etween these ends and plate 118, w ile the billof the hook passes through the space `between the twp ends 131, which will cause any eye which has not properly dropped into recess 115 `of the gripper laws te be brushed into this recess.

While roller 109 is riding up to cam surface 1 25 as described above, roller 106 .wlll ride on cam surface 132, which owing ,to its incline will throw slide 117 with a sud en impulse forward, following the forward movement of the ripper, whereafter .the pusher will (be wit. drawn `quickly by spring 108 before v,the ipper has started for its return motion. lgliis forward motion .of the pusher is necessary-for the following reason: If from any cause .the hook feeding mechanism should fail to deliver a hook at the proper time or the gripper should fail to seize the hook, the .eye would remain at the end of the eye feed in its seat sbpwn in Fig. 28. As the eye feed keeps on delivering another eye to the end of the'eye feed, this next eye would not be able to push the rst eye from its seat in Fig. 28, since the latter eye can only be removed by lifting it from its seat in the direction in which the hooks pass the eye feed, that is in Fig. 29 from the right to the left. If now as described above the pusher follows the gripper in its for-v ward motion, it will strike an eye, accidentally remaining in its seat in the same direction a hook would strike it, lift it from its seat and cause itito drop into the hole 133 provided for this purpose Ain table 5, thus lclearing the eye feed for the nextl eye n agre bent to` run in parallel to the sewing plate 5 soA to be delivered. Afterl roller 106 has passed 101ml surface 132 it will ride again on cam surface 119, ready to perform another cycle of operations, While roller 109 will roll down from cam surface 125, thus withdrawing the gripper jaws from the sewing position of the hooks and eyes into the position ,to seize the next hook. Before the gripper A1s .withdrawn from the position above referred to, gripper larms 111 and 112 will come again into Contact with the elevated portions 121 and 123 of disks 102 and 103 respectively, which will cause the gripper jaws to ppen -and to let go the pair of hooks `and e es placedon the card ready to be re-Y ceive bythe presser foot as above described.

Tzhe c 'ard mechanism which is shown in Figs, 1, 3, 4, 19 and 20 comprises e following parts In Fig. 19, 5 1s the gewin tahleon which .and Within which the card ceding mechanism is mounted. The c ard is placed on table 5, with its end flush with .mar in stop 9 2, to be received by pick up .roll 8 5 (Fig. 3). Fig. 19 is a right slide, and Fig. 20 a left side view of the card shown 1n Fig. 3. On main shaft. 7 of t e machine is mounted cam 162 provided with two recesses 163 and 164. Roller 165 of forked arm 166 suitably disposed to roll on the surface of cam 1.62. The other 4end of forked arm 166 is linked to a rockin lever 17.0 loosely mounted yon shaft 167 w ich is yournaled in sewing table 5 and has'xed vto it ratchet wheel 168 and spur wheel 169. o the `other end of rocking lever 17.0 is pivoted pawl 171 engaging in ratchet wheel 168, so that when roller 165 has rolled into recess 163 l.or 164 by means .of tension spring 172 attached to forked 'of the arrow. The rotation of ratchet wheel 168 and spur wheel 169 is transmitted by the idler 173 to spur wheel 174, mounted on shaft 177, and'thence by the idler 175 to spur wheel 176, mounted on shaft 178. Shaft 178 carries on the other side of table 5 (shown in Fig. 20) spur wheel 182'in mesh with the idlers 179 and 180 which in turn are in mesh with spur wheel 183 fas- ,tened on shaft 181, the other end of which may be seen in Fig. 19. Inside of sewing `table 5 ismounted o n shaft 178 ro-ller 184 (Fig. 1) and on shaft 181 roller 185 having art ,of its circumference recessed (Fig. 20 1n dotted lines). The diameter o f roller 185 is in .the same proportion to that of roller 184, as the diameter of spur wheel 18S is to .that of spur wheel 182. Both rollers are mounted tclose enough to each other that a card inserted between will -be picked up -after the recessed portion 149 of roll 185 i has passed roll 184, and be conveyed by both rolls to the next rolls. On shaft 177 are mounted inside lof sewing table 5 rolls 186 and 187 against which bear the upper feeding rolls 188 and 189 mounted in bell cranks 190 and 191, respectively, the rolls being heldin their operative position by springs 192 and 193, respective attached to ,t e other arms of sald bell cranks. On 'shaft 167 are mounted inside Yof table 5 two lower feed rolls 147 and 148 (partly shown in Fig. 4) against which bear upper feed rolls 194 and 195, respectively, mounted on shaft 199 4 (Fig. 3) which is journaled in the two cor- `The track of the 'cards is defined b responding arms of bell cranks 197 and 200. Both of these bell cranks are suitabl pivoted, one on each side of table 5 an hold upper feed rolls 194 and 195 in operative position by means of tension springs, one of which is shown in Fig. 19 at 198. Upper feed rolls 194 and 195 are positively driven b ear wheel 196 fastened at one end of siia 199 and in mesh with gear wheel 168. plates 118y under which the cards sli w en fed by the rolls 184 and 185 into t e machine, their proper enga ement under lates'118 being secured by aving the en of these plates, which the cards approach iirst, slightly bent up (Fig. 19, left end), whereafter they are conveyed by the feed rolls above described through the machine in the direction indicated by the arrow in Fig. 3.

The step by step movement of the cards along their track in accord with the sewing process is obtained in the following manner: The whole machine is timed so that on one revolution of shaft 7 and shaft 101, one pair of hooks andeyes is placed by the gripper on the card. Since each hoo and eye has two sewing eyes, two stitches have to be made by the machine for each pair of hooks and eyes, and consequently two feeding steps of the card feed are necessary for each pair of hooks and eyes. For this purpose recesses 163 and 164 are provided 1n cam 162 exactly opposite to each other, so that'when shaft 7 makes one half revolution, rocking lever 170 connected with forked arm 166 will move ratchet wheel 168 one tooth, which ste is through thetransmission by means of) the gear wheels 169, 174 and 176 to their respective feed rolls equal to the distance between two sewing eyes of the hook and eye.

On both ends of shaft A181 (Figs. 1, 2 and 3), are fastened toothed wheels 202, a detail view of which is shown .in Fig. 21. Near and in parallel with toothed wheel 202 is disposed the yoke 203 which is a part of lever 205 fulcrumed at 209 onl sewing table 5. On yoke 203 is provided screw 204 of suitable size to engage in thenotches of toothed wheel 202, when lever 205 is drawn downward by tension spring 210. To the remets free end of lever 205 is pivoted bar 206I which in turn is pivoted at its upper end to arm 207 in Figs. 2 and 13. Arm 207 is fastened on shaft 208 journaled in bracket 211 fixed to cross bar 9 of frame 2. At one end of shaft 208 is further fastened arm 78 engaging with its slotted free end pin 79 of slide 66 of the eye feed described before while at the other end of shaft 208 is fixed arm 59 engagin with its slotted free end pin 58 of slide 5 of the hook feed also described before. lt will now be seen that if toothed wheel 202 revolves with shaft 181. in the direction indicated by the arrow in Fig. 21, yoke 208 and its lever 205 will perform a rocking motion, owing to screw 204 dropping into the different notches of toothed wheel 202 which rockin motion is transmitted by bar 206 to sha t 208 and arms 78 and 59y (Fig. 13 This will cause the slide 66 to operate t e ege feeding device, and slide 57 to operate t e hook feeding device, the timing of both devices being such that at the same time when an eye is fed to the end of the eye feeding apparatus, a hook is fed to the end of the hook chute into the proper position to be received by the grilpper.

t has been stated above that the forward motion of one tooth of ratchet wheel 168 (Fig. 19), corresponds with one feeding step of the card and it has been also stated that two feeding steps of the card are .necessary for one pair of hooks and eyes. The gearing from ratchet wheel 168 to shaft 181 through gear wheels 169, 174, 176, 182 and 183 is chosen so that when ratchet wheel 168 has been movedforward by its pawl 171, two teeth, toothed wheel 202 on shaft 181 has moved one tooth in the direction of the arrow, so that .rocking members 205 and 206 operating the hook and eye feed described above, have completed one full up and down stroke. The result of this is that one single hook and eye has been fed by the hook and eye feeding devices into position to be placed by the gripper on the card. Since in this machine twelve pairs of hooks and eyes are to be sewed in one row on one side of the card, toothed wheel 202 is provided with twelve teeth.

After one row of hooks and eyes has been sewed to the card, two closing stitches have to be made by the machine into the card, and furthermore two other stitches have to be made at the beginning of the next card to properly fasten the thread in the card. The four feeding steps of the card feeding mechanism necessary for these idle stitches have to be made without operating the hook and eye feed. Since now four feeding motions of the card feed correspond with the feeding of two pairs .of hooks and eyes of one row kI provide on toothed wheel 202 (Fig, 21) a notch 212 equal in its size to the space which two teeth occupy on the circumference of wheel 202, so that while screw 204 passes through notch 212,the hook and eye feedin devices will remain at rest, while the car feed moves the card four steps for the four idle stitches mentioned.

above. The recessed portion 149 of pick up roll 185 is placed so, relatively to notch 212 of wheel 202, that it will pick up the cards placed on thc table,'so that two idle stitches are' made at the end of one card and two at the beginning of the following card.

The sewing mechanism as faras it comprises the loopers mounted within sewing table 5 are not shown in the drawings, since none of my improvements relates to these parts of the machine. The looper mechanism which may be of any Lind is operated by forked arm 213, suitably operated by cam 214 mounted on shaft 215 which also erates arm 216, imparting rockin motion to lever 45 in engagement wit the needle bar 44 as described above, (Fig. 2).

Rotating motion is transmitted to shaft 215 from the main shaft 7 (Fig. 3) through the gear wheels 217 mounted on shaft 7 and idler 218 and pinion 221 mounted on shaft 215.

The eye hopper is shown in detail i1. Figs. 33 to 36 and its location in the machine in Figs. 1, 2 and 4. The hopper has a conical shape with an opening 134 at the tapered end, as may be seen in Figs. 1 and 2, through which it is charged. lThe other end of the hopperis closed by a cover 135, the particular features of which are to be described later on. Cover 135 is fastened centrally to shaft 136 which is journaled 1n bracket 3 mounted on frame 2 as before mentioned. Shaft 136 is driven by pulley 137 through belt 138 running over pulley 139 fastened on shaft 101 (Fig. 3). If desired the hopper may be thrown out of operation by disengaglng the clutch connecting its shaft 136 with pulley 137. For this reason shaft 136 (Fig. 2) is protruding on the left hand end beyond pulley 137 which is loosely fitted on this shaft. To this end of shaft 137 is splined collar 140 suitably shaped at the end facing pulley 137 to engage the hub of this pulley, which hub is correspondingly shaped for this purpose. Collar 140 is shifted on shaft 136 by means of forked arm 233 engaging it with its forked end and fastened to shaft 230 at its other end. Shaft 230 is suitably journaled in bracket 3 to have axial motion and guided'` by. arm 232 loosely fitted on shaft 136. 0n operating shaft 230 by means of hand lever 141, shaft :136 may be thus thrown into and out of engagement with pulley 137.

When the ho per has been charged, the eyes will drop uring its rotation into beveled slots 142 of cover 135, the particular shape of which is shown in detail in Figs.

33 to 35. 0n approaching the outer diame,.

ter of cover 135 the slots are contracted and assume a rectangular cross-section as shown at 143 (Fig. 36). If now an eye drops into one of these slots it will fall down into the contracted portion 143 of the slot and would commence to fall out of the hopper when the slots arrive beneath the axis ot rotation of the hopper, if rail 63 were not provided which surrounds the lower half of 'cover 135 in the middle line'of slots '143 as close as mechanical reasons will allow, as may be seen in Figsf2, 4, 3 3 and partly in Figs. 35 and 36.

Rail 63 is thin enough to pass freely between the sewing e es ofthe eye so that if one of the eyes ten s to fall through one of the slots 143 with the sewing eyes first, this eye will ride on rail 63 as shown in Fig. 33. As may be seen in this figure the eye will not drop out of slot 143 entirely owing to the close position of rail 63 to cover 135, but will be carried along rail 63 by the edges of the slot 143 until it arrives at the bead 64 of rail 63 which is suitably shaped at the end 144 to cause the lower edge of slot 143 carrying the eye, to slip same over the bead as may be seen in Figs. 35 and 36, whereafter the eye will drop entirely out of slot 143, ride on bead .64 and straddle down to the eye feeding device described before.

It will be seen without further discussion that no eye is thus able to drop out of the hopper unless it is in the proper position to be received by the rail, that is with the sewing eyes first. lAny eye having another position in slot 143 cannot ride on rail 63 and will be simply carried along in its slot, until it drops back into the hopper as soon as its slot arrives at the upper half of disk 135.

While I have shown in the drawings rail 63 where it surrounds the hopper of equal -thickness throughout so it may receive an eye from the slots with the sewing eyes first at any oint, I do not wishl to limit the scope o this invention to-this particular structure. The spirit of this particular invention as claimed later on is, that suitable means are provided close to the hopper at places where an eye may drop out of the slots, and that these means owing to their structure may also normally yprevent the dropping of the eyes out of their slots entirely even if in proper position, and that only at most suitable places these means may be of such shapes as to allow the dropping out of the eyes only in a predetermined position and to receive same in such position. The structure of these means, as shown in the drawings, is merely a specific form-
